Problem summary

  • APAR NUMBER:  PJ40215
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  CONTINUOUS DATA COLLECTION (CDC)
    SHIPPED IN PUT:  9
    
    ABSTRACT:
    CDC reports incorrect CEC utilization for logical partitions
    using specialty processors with PJ30885 applied

    COMMENTS:
    CDC code calculates CEC utilization percent by dividing the
    total utilization of all processors assigned to the LPAR by the
    total count of general purpose processors in the CEC. For LPARs
    with specialty processors assigned this will result in
    incorrect CEC utilization percent values.
    

Problem conclusion

  • SOLUTION:
    The chosen solution is to update CDC to report LPAR CPU counts
    and utilization values solely based upon the shared general
    purpose processors. With this APAR applied, the CPUs column
    will be the number of shared general purpose CPUs assigned to
    the LPAR. The three utilization columns (LPAR utilization,
    Capped utilization percent, CEC utilization percent) will
    represent utilization of only the shared general purpose
    processor assigned to the LPAR.
    
    LPARs which have dedicated processors assigned or have only
    specialty processors assigned will be reported upon but their
    values (CPU count and utilization values) will be zeros.
    
    COREQS: NO
    None.
